Run the engine under load (in gear with a
propeller installed) as follows.
1)
First 10 minutes:
Run the engine at the lowest possi-
ble-speed. A fast idle in neutral is
best.
2)
Next 50 minutes:
Do not exceed half throttle (approxi-
mately
3,000 r/min). Vary engine
speed occasionally. If you have an
easy-planing boat, accelerate at full
throttle onto plane, then immediately
reduce the throttle to 3,000 r/min or
less.
3)
Second hour:
Accelerate at full throttle onto plane,
then reduce engine speed to three-
quarter throttle (approximately 4,000
r/min). Vary engine speed occasional-
ly. Run at full throttle for one minute,
then allow about 10 minutes of opera-
tion at three-quarter throttle or less to
let the engine cool.
4)
5)
Third through tenth hours:
Avoid operating at full throttle for
more than 5 minutes at a time. Let the
engine cool between full-throttle runs.
Vary engine speed occasionally.
After the first 10 hours:
Operate the engine normally. Use
only straight gasoline in the fuel tank.
The oil injection system provides
proper lubrication for normal opera-
tion.
